Rather than having TT compete with BoClean and my AV when I boot up, I found disabling TeaTimer at startup and manually turning it on is more sensible for my system. I pinned TeaTimer to the Start menu and wait about 30 minutes before enabling.
Winpatrol free version has a delayed start option which can be used to delay the start of Tea Timer for a while at boot up. You can delay it for 30 seconds, 1 minute, or more. Perhaps it will help things somewhat.
